To all whom it may concern:

Be it known that I, Ln ROY WILSON KEL- SAY, a citizen of the UnitedStates, residing at New York, in the county of New York, State of NewYork, have invented certain new and useful Improvements in AutomaticHand Telephones, of which the following is a full, clear, concise, andexact description;

This invention relates to hand telephones provided with impulsetransmittersand adapted for use with automatic telephone systems. Thesehand telephones are particularly, although not exclusively, used by .15telephone repair-men.

The general object of the invention is to provide a new and. improvedautomatic and telephone which has the advantages, among others, ofcompactness, good balancmg, and protection of the impulse transmitterfrom harm.

The invention is characterized in general by the location of the impulsesender on the handleof the instrument intermediate the receiver and thetransmitter; and specifically bythe location of the impulse sender in acavity in the handle and on the same side of the latter on which thereceiver and transmitter are mounted.

The invention will be understood from the following detailed descriptiontaken in connection with the accompanying drawing, in which Figs. land.2 show in perspective two embodiments of the invention.

Referring to both Figs. 1 and 2, the handle portion of the handtelephone is shown at 3 and 3', the receiver portion at 4 and 4', andthe transmitter portion at 5 and 5. These may-be any suitable form.

In the embodiment shown in Fig. 1, the impulse transmitter 6, which ispreferably of thedial type, is mounted on the handle 3, on the same sidethereof as the receiver and transmitter, and intermediate 4 the-latter.In the embodiment shown in Fig. 2, the impulse transmitter 6 is mountedon thehandle 3', on the side opposite to that on which the receiver 4'and the transmitter 5' are located. In both embodiments of theinvention, the handle portion of the instrument is provided with acavity within which the impulse transmitter is mounted and is therebyprotected from injury.

of these buttons is shown at? and 7 in Figs.

1 and 2. The other button, not shown, is similar to button 7 (or 7) andsymmetrically disposed with respect to it on opposite side of thehandle. One of these buttons may, therefore, be conveniently operated bythe thumb and the other by the forefinger. The openings 8 and 8' in theend of each hand telephone allow the line conductors to be led in toterminals on the inside of the instrument.

It is of course understood that the hand telephones herein shown anddescribed may be modified as regards their design and form withoutdeparting from the spirit of the invention as defined in the claims.

What is claimed is:

1. In an automatic hand telephone, the combination of ahandle, atelephone receiver and a telephone transmitter secured to opposite endsthereof, and an impulse transmitter mounted on the handle inter mediatethe receiver and transmitter.
